Hejhal's algorithm and computational methods for non-classical Maass wave forms
I think the paper on his home page is the same as the one he posted to the ArXiv: sites.google.com/site/mboris |

central/critical/special values of L-functions terminology
I wrote the question in the "arithmetic" normalization, with $s$ going to $w+1-s$ in the functional equation. I know that "most" L-functions are not motivic, but my understanding is that the concept of special/critical values only makes sense for motivic L-functions. You wouldn't say, for example, that every integer is a critical point for the L-function of a Maass form. There are times when you want to normalize the L-function so that $s$ goes to $1-s$, but this is not one of those times. |

Is there an explicit expression for the imaginary part of some non-trivial zero of zeta,
Greg, Not even close: we can't even prove that for degree 2. It is not even known that the members of the Selberg class, of degree 2 or more, have Euler products whose local factors are the reciprocal of a polynomial. (I saw something along those lines -- I forget the details -- from Kaczorowski and Perelli, but what I wrote is definitely true for "degree more than 2.") |

Is there an explicit expression for the imaginary part of some non-trivial zero of zeta,
Paul, It is conjectured that the factorization of L-functions into primitive L-functions is unique. This follows from the Selberg Orthonormality Conjecture. Unique factorization implies that you can't "split up" the cancellation of zeros of one L-function by part of the zeros of several different L-functions. So (assuming appropriate conjectures) the Artin L-function can only be entire if there is a cancellation of actual L-functions in the numerator and denominator. |

If an Artin L-function was genuinely a ratio, and not a product, of other L-functions (in other words, if it had infinitely many poles) then it does not deserve to be called an L-function! For this discussion I think it makes sense to assume all reasonable conjectures. |

Small index subgroups of SL(3,Z)
Great answer. I wish I could "accept" two answers. |
